Does atmospheric CO2 cause warming? Absolutely, otherwise Earth would be frozen solid. So the question is how much warming does 400 ppm cause (2013)? How about 300ppm (1900)? Does an increase in C02 automatically cause warming?

Don't tell me this, tell it to the numbskull on this thread who insists that CO2 has nothing to do with climate. Perhaps Mr. Media can explain why Venus has surface temperatures that can melt lead if CO2 and CH4 don't influence climate.

I like to remind people that we are in an Ice Age so a little warming might not be a bad thing.

I find the case Michaels and Balling make convincing - that there is a small century plus warming trend, and that it's just as likely to be somewhat beneficial to parts of the world as harmful to others, and that the best data suggest that the effects are marginal.

Here’s a clue :CO2 does NOT affect the Earth’s climate. regardless of what you and your liberal mainstream media ,UN , and fake global warming science say.

CO2 does NOT affect the Earth’s climate.

CO2 levels do NOT affect the Earth’s climate.

CO2 does NOT affect the Earth’s climate.

you say C02 does affect the Earth’s climate. you buy into the socialist lies . so you want us enslaved to the government and to socialism. they create this lie that C0 affects climate so that they can control us and our businesses . and you are trying to propagandize , to further that lie.

You are a joke and a liberal/democrat

your name calling just further confirms you are a complete idiot and a socialist

you have the IQ of lint

The Earth is cooling and will get much colder in the coming decades because of Solar cycle 25. the Sun does affect climate C02 does not , get it yet moron? you are the dumbest idiot just like all the leftist idiots.
